A gas-tight integral premium connection with high tensile rating (90% of pipe body strength) and torque capacity, making it ideal for production casing in the Shale plays.
The tapered two-step thread design means that it stabs deep with very low risk of cross-threading. The gas-tight metal-to-metal seal location (in front of the torque shoulder) also provides a good protection from handling damages.
"VAM SG was specifically developed to offer customers in US Shale plays like Haynesville a unique solution for the production casing string, offering at the same time the tensile strength, the torque capacity and the clearance needed for the long laterals. It enabled to replace the mixed string design, that consisted in a Threaded and coupled at the top, and a semi-flush in the lower section, as there was no integral connection that could meet all the performances. Thanks to VAM SG, the well design and operations were made easier, without the need for cross-overs, and a single inventory of joints and accessories, which saved time and money for operators."
